Along with the renewed interest in the Austrian school of economics over the last two decades, important advances have been made in applying its princples to concrete issues that typically face market economics. However, very little has been done in the area of externalities and the concept of social efficiency. The overarching purpose of this book is to establish a sound theoretical basis for further empirical and public policy analysis in the area of externalities. In order to do this, a general theory of welfare economics is required. The author offers an alternative to the conventional neoclassical welfare paradigm -- his construct does not include perfect competition or general equilibrium. After the author develops his theory of welfare economics, he interprets externalities in light of the theory and discusses policy remedies and directions for further research.

Foundations of Bayesianism is an authoritative collection of papers addressing the key challenges that face the Bayesian interpretation of probability today.
Some of these papers seek to clarify the relationships between Bayesian, causal and logical reasoning. Others consider the application of Bayesianism to artificial intelligence, decision theory, statistics and the philosophy of science and mathematics. The volume includes important criticisms of Bayesian reasoning and also gives an insight into some of the points of disagreement amongst advocates of the Bayesian approach. The upshot is a plethora of new problems and directions for Bayesians to pursue.

The book will be of interest to graduate students or researchers who wish to learn more about Bayesianism than can be provided by introductory textbooks to the subject. Those involved with the applications of Bayesian reasoning will find essential discussion on the validity of Bayesianism and its limits, while philosophers and others interested in pure reasoning will find new ideas on normativity and the logic of belief.

Profits in the Long Run asks two questions: Are there persistent differences in profitability across firms? If so, what accounts for them? This book answers these questions using data for the 1000 largest US manufacturing firms in 1950 and 1972. It finds that there are persistent differences in profitability and market power across large US companies. Companies with persistently high profits are found to have high market shares and sell differentiated products. Mergers do not result in synergistic increases in profitability, but they do have an averaging effect. Companies with above normal profits have their profits lowered by mergers. Companies with initially below normal profits have them raised. In addition, the influence of other variables on long-run profitability, including risk, sales, diversification, growth and managerial control, is explored. The implications of antitrust policy are likewise addressed.

This study analyses the functioning of the peasant economy in Peru in the context of the present predominantly capitalist system. The central themes are the economic relationships of the peasantry to the rest of the economy of the country and the role of the peasant economy in the entire system, together with the changes that have taken place in that role over time. These themes are investigated by means of a study in detail of a sample of peasant communities in the most traditional and backward region of Peru, the southern sierra. The historical process has generated in Peru one of the most extreme cases of inequality, rural poverty and cultural duality. Nowhere else does the notion of 'economic duality' seem more applicable. Thus an investigation of the case of Peru has methodological value for the understanding of the peasant economy throughout Latin America, and the results of this survey have important implications for the whole region.

This volume brings together leading scholars to make connections between efficiency and a number of diverse areas of current interest to economists. Included are new results concerning aggregation of technical efficiency, sources of productivity growth in U.S. manufacturing, intellectual property rights, and the determinants of successful mergers.

Orio Giarini The "Geneva Association" (International Association for the Study of Risk and Insurance Economics) was founded in 1973. The main goal was to stimulate and organize objective research in the field of risk, uncertainty, and insurance, in a world in which such issues were clearly becoming of greater and greater relevance for all economic actors. This was a pioneer ing effort, especially as economic theory and the teaching of economics were still anchored to the key notion of general equilibrium under an assumption of certainty. Thus, we had to start our work almost from scratch. One of the first initiatives was to bring together in Geneva, in June of 1973, all the academics in Europe already involved in risk and insurance economics. We found eight from five different countries who never had met before. This seminar chaired by Raymond Barre, the first president of The Geneva Association, was the first of an annual series that became known as the seminar of "The European Group of Risk and Insurance Economists." Since then more than 100 economists from most European countries as well as participants from two other continents and in particular from the United States have taken part in this seminar."

In order to survive as a social institution a firm needs a constitutional social contract, even though implicit, among its stakeholders. This social contract must exist if an institution is to be justified. The book focuses on two main issues: To find out the terms of the hypothetical agreement among the firm's stakeholders in an ex ante perspective and to understand the endogenous mechanism generating appropriate incentives that induce to comply with the social contract itself, as seen in the ex post perspective.

For people interested in risk management, medical activity represents a stimulating field of study and thought. On the one hand, progress in medical knowledge and technology tends to reduce the risks to survival that individuals would face in the absence of appropriate diagnostic or therapeutic instruments. On the other hand, new medical technologies simultaneously create their own specific risks, sometimes simply because their effects are less well-known than those of established ones. In a sense any medical progress simultaneously generates new risks while destroying old ones. Moreover, unlike many financial risks that can be either divided or transferred to others (e.g. through diversification, insurance or social security) the personal aspects of medical risks are by essence indivisible and non-transferable. As a result, they are in a sense more threatening than financial risks for risk averse patients. These two facts explain and justify the growing interest in risk economics for the fields of medical decision making and health economics. In Risk and Medical Decision Making, part 1 is developed inside the expected utility (E-U) model and analyses how comorbidity risks affect the well-known "test-treatment" thresholds. Part 2 is devoted to a specific non E-U model with the same purpose: how would one define a threshold in this context and how would one value a diagnostic test? In each of these two parts both diagnostic and therapeutic risks are considered.

R. H. Coase Duncan Black was a close and dear friend. A man of great simplicity, un worldly, modest, diffident, with no pretensions, he was devoted to scholarship. In his single-minded search for the truth, he is an example to us all. Black's first degree at the University of Glasgow was in mathematics and physics. Mathematics as taught at Glasgow seems to have been designed for engineers and did not excite him and he switched to economics, which he found more congenial. But it was not in a lecture in economics but in one on politics that he found his star. One lecturer, A. K. White, discussed the possibility of constructing a pure science of politics. This question caught his imagination, perhaps because of his earlier training in physics, and it came to absorb his thoughts for the rest of his life. But almost certainly nothing would have come of it were it not for his appointment to the newly formed Dundee School of Economics where the rest of the. teaching staff came from the London School of Economics. At Glasgow, economics, as in the time of Adam Smith, was linked with moral philosophy. At Dundee, Black was introduced to the analytical x The Theory o/Committees and Elections approach dominant at the London School of Economics. This gave him the approach he used in his attempt to construct a pure science of politics."

Professor Sten Malmquist constructed the Malmquist quantity index and in doing so developed a distance function defined on a consumption space. This function is the consumer analog to the Shephard input distance function of producers and is used in ratio form to define the quantity index. This volume contains new contributions based on Malmquist's work nearly 50 years ago and provides modern perspectives on the value of this research.

As the demand for environmental quality is increasing and as the current GATT rules monitored by the WTO are not very suitable for environmental protection, either a new international environmental organization may be formed soon or new environmental regulations may be added to GATT. In either case, understanding of the interactions between trade and the environment will be vital. Trade and the Environment presents both the theoretical and empirical exposition of (i) the impact of trade liberalization on environmental quality; (ii) the impact of environmental regulations on international competitiveness; and (iii) strategic trade and environmental policies. An important feature of Trade and the Environment as compared to earlier books is that it brings together the reciprocal interactions between trade and the environment. It can be used as the main or complementary textbook for a course on trade and the environment.

Information, Innovation and Impacts - a joint project between the Program of Research in International Management and Economy (PRIME) at the University of Ottawa and Statistics Canada - brings together economic, social and statistical views of the impacts of the innovative uses of information. It examines the costs as well as the benefits of rapidly expanding availability of data, of information, and of codified knowledge, and it provides suggestions for future work and research. This project fits into an on-going research program at Statistics Canada to develop indicators for science and technology (S&T) in a more coherent manner, and it fits into the research program of PRIME to better understand the dynamics of innovation in an information economy. Together, Statistics Canada and PRIME strive to tell the story of the activities in S&T systems, their interactions, and the outcomes as actors go about the generation, transmission, or mediation of knowledge, information, and of data, as part of the effective functioning of the system.

Uncertain Decisions: Bridging Theory and Experiments presents advanced directions of thinking on decision theory - in particular the more recent contributions on non-expected utility theory, fuzzy decision theory and case-based theory. This work also provides theoretical insights on measures of risk aversion and on new problems for general equilibrium analysis. It analyzes how the thinking that underlies the theories described above spills over into real decisions, and how the thinking that underlies these real decisions can explain the discrepancies between theoretical approaches and actual behavior. This work elaborates on how the most recent laboratory experiments have become an important source both for evaluating the leading theory of choice and decision, and for contributing to the formation of new models regarding the subject.

It is beyond any doubt that East-Central European countries such as Czech Republic, Hungary, Poland and Slovakia has dramatically changed its shape through its radical transition from centrally planned to the market economies in last 7 years. Many economists divide the process of economic transformation into areas of Stabilization, Liberalization, and Privatization/Restructuring. The traditional view is that stabilization and liberalization can be achieved rather quickly-by balancing budgets, balance of payments, tightening money supply, freeing prices and liberalizing trade-but that the area of privatization is one that could be moved to the future and will require much more time. Until 1991, none of the post-communist nations except former East Germany (which had a large decree of support from West Germany) had succeeded in privatizing large numbers of enterprises, even though more than two years had passed since the changes in government in these nations. The privatization has been, however, seen as an extremely important part of reform package together with stabilization and liberalization especially in the Czech Republic from the very beginning. The Czechs originally as a part of the Czechoslovak Federal Republic embarked on an unprecedented path that should have lead not only to stabilization and liberalization, but also to very rapid, mass privatization of its sector of large enterprises that have dominated its economy to an extreme extent.

Empirical Studies In Applied Economics presents nine previously unpublished analyses in monograph form. In this work, the topics are presented so that each chapter stands on its own. The emphasis is on the applications but attention is also given to the econometric and statistical issues for advanced readers. Econometric methods include multivariate regression analysis, limited dependent variable analysis, and other maximum likelihood techniques. The empirical topics include the measurement of competition and market power in natural gas transportation markets and in the pharmaceutical market for chemotherapy drugs. Additional topics include an empirical analysis of NFL football demand, the accuracy of an econometric model for mail demand, and the allocation of police services in rural Alaska. Other chapters consider the valuation of technology patents and the determination of patent scope, duration, and reasonable royalty, and the reaction of financial markets to health scares in the fast-food industry. Finally, two chapters are devoted to the theory and testing of synergistic health effects from the combined exposure to asbestos and cigarette smoking.

The aim of this book, Future of the Telecommunications Industry: Forecasting and Demand Analysis, is to describe leading research in the area of empirical telecommunications demand analysis and forecasting in the light of tremendous market and regulatory changes. Its purpose is to educate the reader about how traditional analytic techniques can be used to assess new telecommunications products and how new analytic techniques can better address existing products. The research presented focuses on new products such as Internet access and additional lines and new techniques such as hazard modeling, adaptive forecasting and neural networks. The scope of this volume includes new telecommunications products, new analytical techniques, and a review of market changes in the US and other countries. Some of the most critical questions facing the industry are addressed here, such as the impact of competition, customer churn, rate re-balancing, and early assessment of new products. The research includes a variety of different countries, products and analytic tools.

While income redistribution is one of the most important functions of modern governments, the world has changed greatly since this first edition of Economics of Income Redistribution was published in 1983. Pension systems and medical programs are in a state of crisis in many parts of the world and the general political mood is shifting away from income redistribution. Economics of Income Redistribution (2nd edition) brings this work up to date by discussing the economic and political aspects of income redistribution. It examines the classical moral objective of redistribution to assist the poor, as well as income transfer for pensions, education and intra-family gift giving.

Markets, Information and Uncertainty is a collection of essays by leading theorists offering powerful new insights on the role of uncertainty and information in today's market. This book features Kenneth Arrow on information and the organization of industry, Roy Radner on new technologies, Graciela Chichilnisky and Frank Hahn on human-induced uncertainty, Geoffrey Heal and Walter Heller on the creation of new markets and Edmund Phelps on unemployment. It is an authoritative collection offering imaginative and fresh approaches to economic theory.

This volume brings together eight original essays selected to provide an overview of the developments in the spatial theory of voting. The spatial theory of self-interest and explores the consequences of this assumption for elite behaviour and for the choices voters make in representative and direct democracies. The book summarizes work in eight major areas: elections with possible entry by new candidates who have policy preferences, experimental testing of spatial models of committees and elections, elections with imperfect information about voting intentions, voting on alternatives that are linked to future decisions, elections with candidates who have policy preferences, experimental testing of spatial manoeuvres designed to alter voting outcomes, elections with experimental testing of spatial models of committees and elections, elections with imperfect information about voting intentions, voting on alternatives that are linked to future decisions, elections with more than two candidates under different election rules, and bureaucratic efforts to manipulate referendum voting. Recognized scholars in these areas summarize the major results of their own and others' work, providing self-contained discussions that will apprise readers of important recent advances.

There have been systematic attempts over the last twenty-five years to explore the implications of decision making with incomplete information and to model an 'economic man' as an information-processing organism. These efforts are associated with the work of Roy Radner, who joins other analysts in this collection to offer accessible overviews of the existing literature on topics such as Walrasian equilibrium with incomplete markets, rational expectations equilibrium, learning, Markovian games, dynamic game-theoretic models of organization, and experimental work on mechanism selection. Some essays also take up relatively new themes related to bounded rationality, complexity of decisions, and economic survival. The collection overall introduces models that add to the toolbox of economists, expand the boundaries of economic analysis, and enrich our understanding of the inefficiencies and complexities of organizational design in the presence of uncertainty.

It is difficult to overstate the importance of personal consumption both to individual consumers and to the economy. While consumer&, are recognized as valuing market goods and services for the activities they can construct from them in the frameworks of several disciplines, consequences of the characteristics of goods and services they use in these activities have not been well studied. In the discourse to follow, I will contrast knowledge-yielding and conventional goods and services as factors in the construction of activities that consumers engage in when they are not in the workplace. Consumers will be seen as deciding on non-work activities and the inputs to these activities according to their objectives, and the values and cumulated skills they hold. I will suggest that knowledge content in these activities can be efficient for consumer objectives and also have important externalities through its effect on productivity at work and economic growth. The exposition will seek to elaborate these points and contribute to multi disciplinal dialogue on consumption. It takes as its starting point the contention that consumption is simultaneously an economic and social psychological process and that integration of content can contribute to explanation."

Our original reason for writing this book was the desire to write down in one place a complete summary of the major results in du ality theory pioneered by Ronald W. Shephard in three of his books, Cost and Production Functions (1953), Theory of Cost and Produc tion Functions (1970), and Indirect Production Functions (1974). In this way, newcomers to the field would have easy access to these important ideas. In adg, ition, we report a few new results of our own. In particular, we show the duality relationship between the profit function and the eight equivalent representations of technol ogy that were elucidated by Shephard. However, in planning the book and discussing it with colleagues it became evident that such a book would be more useful if it also provided a number of applications of Shephard's duality theory to economic problems. Thus, we have also attempted to present exam ples of the use of duality theory in areas such as efficiency measure ment, index number theory, shadow pricing, cost-benefit analysis, and econometric estimation. Much of our thinking about duality theory and its uses has been influenced by our present and former collaborators. They include Charles Blackorby, Shawna Grosskopf, Knox Lovell, Robert Russell, and, not surprisingly, Ronald W. Shephard. We have also benefit ted over the years from many discussions with W. Erwin Diewert."

People want more from the government. One thing they want more of is a sense of personal safety, at home and at work (Regulation, Fall 1991). People also want the government to quit wasting money. The objective of having the government provide a safer life for us and our children at minimum cost leads logically to looking at policy within the system involving the private sector plus governments at the federal and sub federal levels. Using numerical simulations our book takes an integrated quantitative look at how the various institutions influencing workplace safety lead to the observed levels of illnesses and injuries among U.S. workers. Our innovation is piecing together the mosaic of interactions among workers, employers, state government, and the federal government that is numerically realistic in the sense of using economists' current knowl edge of quantitative connections. Our objective has been to write a Gray's Anatomy, if you will, of how the U.S. economic system, as tempered by government policy, jointly determines employment patterns, wages, and workplace safety levels."

Long before policy analysis emerged as a separate profession with its own graduate schools, economists offered advice about government policies. Positive economics provides the tools for predicting the impacts of prop osed policies; normative economics, especially welfare theory, offers a framework for valuing the impacts of policies in terms of efficiency and simple notions of equity. With the expansion of economic theory into ever wider fields of human behavior, it is no wonder that economists have prominence as teachers and practitioners of policy analysis. Indeed, many economists see policy analysis as essentially applied economics. Though other social scientists might object to this somewhat parochial view, economics and policy analysis share much in commom in terms of develop ment and prospects. The purpose of this volume is to trace these interrela tionships and explore the tensions that they create. Tensions arise for several reasons. Changes in the discipline of econ omics affect the findings, methods, and personnel offered to policy analy sis. For example, on the one hand, the "new institutional economics" appears to be extending the influence of economists to questions involving nonmarket oranizations, while on the other hand, the apparently growing emphasis within the economics profession on creating rather than empir ically testing theory suggests that fewer of the best young scholars will be drawn to policy-relevant research. Within the schools of policy analysis, the drift toward public management may reduce the demand for traditional economic training."
